OfficeScan will not scan all files found under a specific directory on the computer. You can specify a maximum of 256 directories.
By excluding a directory from scans, OfficeScan automatically excludes all of the directory’s sub-directories from scans.
You can also choose Exclude directories where Trend Micro products are installed. If you select this option, OfficeScan automatically excludes the directories of the following Trend Micro products from scanning:
During a Manual Scan, OfficeScan still scans the server installation folder.
InterScan eManager 3.5x
InterScan Web Security Suite
InterScan Web Protect
InterScan FTP VirusWall

InterScan E-mail VirusWall
ScanMail eManager™ 3.11, 5.1, 5.11, 5.12

If you have a Trend Micro product NOT included in the list, add the product directories to the scan exclusion list.
Also configure OfficeScan to exclude Microsoft Exchange 2000/2003 directories by going to the Scan Settings section of Agents > Global Agent Settings on the Security Settings tab. If you use Microsoft Exchange 2007 or later, manually add the directory to the scan exclusion list. Refer to the following site for scan exclusion details:
When you configure the file list, choose from the following options:
Retains current list (default): OfficeScan provides this option to prevent the accidental overwriting of the agent’s existing exclusion list. In order to save and deploy changes made to the exclusion list, select any of the other options.
Overwrites: This option removes and replaces the entire exclusion list on the agent with the current list. After clicking Apply to All Agents, OfficeScan displays a confirmation warning message.
Adds paths to: This option adds the items in the current list to the agent’s existing exclusion list. If an item already exists in the agent’s exclusion list, the agent ignores the item.
Removes paths from: This option removes the items in the current list from the agent's existing exclusion list, if found.
